27 is what percent of 228 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 228 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 228, so we can write it down as 100%=228.
4. We know, that x% equals 27 of the output value, so we can write it down as x%=27.
5. Now we have two simple equations:
1) 100%=228
2) x%=27
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=228/27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27 is what percent of 228

100%/x%=228/27
(100/x)*x=(228/27)*x       - we multiply both sides of the equation by x
100=8.44444444444*x       - we divide both sides of the equation by (8.44444444444) to get x
100/8.44444444444=x
11.8421052632=x
x=11.8421052632

now we have:
27 is 11.8421052632% of 228
